SPECIPICATIONioi-ming part of Letters Patent NO. 355,623, dated January4, 1887.

Application filed April 15, 1856. Serial No. 198,896. (No model.)

. To LZZ 10700712/ it' may concern.-

Be it known that I, ADAM REIQHERT, a citizen of the United States,residing at Tifn, in the county of Seneca and State of Ohio, haveinvented certain new .and useful lmprovements in Drag-Saws, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to certain improvements in log-sawing machines ofthat class in which the device is tted to the log to be sawed andoperated by means of suitable levers; and it has for its objects to givea direct thrust to the saw and elevate the frame as occasion requires,as more fully hereinafter specified.

The above-mentioned objects I attain by the means illustrated in theaccompanying draw ings, in which- Figure l represents a side elevationof my improved machine; Fig. 2, an elevation and part sectional view ofthe same; Fig. 3, an

elevation of the sliding frame of my machine I detached, and Fig. 4 -adetached view of one of the guide-hangers forming part of my improvedapparatus.

The letter A indicates a rectangular beam, which near its forward end isprovided with a spike, B, adapted to set into the log C, so as to keepthe beam and the log in the proper relative positions during theoperation of sawing. f

D indicates a vertical frame, which is provided with ways E, in which isadapted to move a frame, F, forming the rear part of the beam A. Thesaid frame D is provided with a base, G, which rests upon the groundwhen the machine is in position. Y.

The letter H indicates a vertical ratchetrod, forming part of the frameD, and I a pawl adapted to engage the ratchets of said rod, so as tohold the frame in any properlyadjusted position.

To each side of the beam are pivoted or fulerumed the levers K, thelower ends of which are provided with treadles L, bymeans of which thelevers may be operated by foot. The upper armsof thelevers serve ashandles, by means of which they may be operated by hand. L'. v

In the frame F'sournaledaatransverse shaft, M, which is provided withcog-pinions N, which are engaged or intergear with the rack-bars P,secured to the lower ,ends of the operating-levers. Thesepinionsservetomove their shaft in reverse directions when operated by the rack-bars.To the shaft M is secured a pinion or cog wheel, R, which intermesheswith the rear end of a rack-bar, S, to the forward end of which the saw'T is secured.

The respective rack-bars are kept to' their intergearing pinions bymeans of the frictionrollersU, mounted on the angle-brackets V, whichare pivoted to the shaft M.

W indicates a seat mounted upon the beam A, upon which the operator sitswhile working the saw. f

The operator, in manipulating the machine, takes his position upon theseat, the beam being arranged in connection with the log, as shown inFig. l of the drawings. Then by operating the levers by foot and hand,through the reversely-v operating gearing, the saw is thrust back'andforth as required. To elevate the saw and adjust it to its work, thepawl and ratchet-bar are brought into use, the pawl serving to hold theframe to any desired position upon the ratchet-bar.Y

Having thus described my invention, what Iclaim, and desire to secure byLetters Patent, 1s-

1. rPhe combination, with the horizontal beam A and the upright beam towhich it is secured, of the levers K K, pivoted to' said beam A, therackbars P P, pivoted tosaid levers, the cog -pinions N N, secured tothe common shaft Mandintergearing with said rack-bars, the cog-wheel R,mounted on said shaft M, and the rack-bar S, with which said wheel Rmeshes, the said rack-bar carrying the saw, to which it gives areciprocating motion, substantially as specified.

2. The combination, With the rack-'bars P P and S and the cog-pinions NN and wheel R, of the friction-wheels U, mounted on suitable arms andbearing upon the respective rack-bars to ,hold them ingearing with the Icogged pinions and wheel,- substantially as and for thepurposesspecified. Y

3. The combination, with the vmain frame IOO D and beam A, of thesliding frame F, the In testimony Whei'eofIaix my signature inoog-pinions N N, and Wheel R, mounted on aV presence of t-wo Witnesses.common shaft, M, journaled in the frame F, the rack-bars P P and theiroperating-levers, ADAM REICHERT.
